Global Class Change: I Became the God of Wealth, and Gold Coins Conquer All

Lin Xuan discovers that he has been reborn on the day of his class transfer exam. But the result is completely different from his previous life. Lin Xuan was supposed to get a civilian class, but instead he becomes... the God of Wealth! The more gold coins I have, the stronger I get! The stronger I get, the more gold coins I earn! The snowball keeps growing and growing. Maybe because Lin Xuan died so miserably in his previous life, not only does he awaken a powerful class, he also gets a powerful System: the Universal Investment System! I invest in you, and you'll become a level 100 Sword Immortal! I invest in you, and you can take down this goblin! I invest in this goblin, and it can take you down! Invest to earn gold coins, then use those coins to crush your enemies! So you're a hidden boss? You think you're tough? So you're the Peerless Sword Saint? You can cut through anything? No problem. I've got plenty of gold coins. I'll bury you in them! That year, monsters broke through humanity's defenses and went on a killing spree in the safety zones. With the survival of the human race at stake, one genius after another stepped forward to fight for humanity! They drove back, subdued, and wiped out the monsters, explored the Abyss, uncovered the world's secrets, and achieved one glorious victory after another!
